Camera lens scratch question

The glass covering the rear camera on my iPhone 4 has gotten slightly scratch and I'm afraid it's affecting the quality of the pictures and video I take. Is that small round piece of glass replaced if I were to replace the rear panel, or is it attached to the camera (meaning I'd have to replace the camera unit, too)? Thanks!

It looks like that there is a lens attatched to the rear panel, along with one on the camera, iFixit's photo's aren't close enough to be entirely sure, but you could check yourself if you just want to remove the 2 screws on the bottom of the device, and take off the panel
